How to test these changes in your application

1. Add the Shopware flex endpoint in your composer.json to https://raw.githubusercontent.com/shopware/recipes/flex/pull-75/index.json.

   # When jq is installed
   jq '.extra.symfony.endpoint |= [ "https://raw.githubusercontent.com/shopware/recipes/flex/pull-75/index.json" ] + .' composer.json > composer.tmp && mv composer.tmp composer.json

   or manually

   "endpoint": [
       "https://raw.githubusercontent.com/shopware/recipes/flex/pull-75/index.json",
       "https://raw.githubusercontent.com/shopware/recipes/flex/main/index.json",
       "flex://defaults"
   ]

2. Install the package(s) related to this recipe:

   composer req 'shopware/administration:^6.6'
